Is the force on matter due to gravity quizlet?
Gravity is a force of attraction between objects due to their masses. Gravity can change the motion of an object by changing the objects velocity. All matter has mass and gravity is affected by the mass of matter.
What are the two components of orbital motion?
Orbital motion has two components – horizontal and vertical. Horizontal motion propels the object forward and vertical free fall pulls the objectdownward toward the center of gravity of the larger mass.
What depends on the distance between an object and the center of the Earth?
The gravitational force between an object and earth is inversely (squarely) related to the distance between the object’s and earth’s center. The acceleration of gravity experienced by objects located near to (and far from) the earth depends on the mass of the object.
Does gravity depends on the material of the objects?
o Gravity depends on the material of the objects. o Gravity is not a force because it can’t move objects. o Gravity is a force because a force is a push or a pull. o The moon has less gravity than the Earth because it has less mass than the Earth. o The moon has less gravity than the Earth because it has no atmosphere.
What are the 3 motions of the moon?
Motions of the Moon
- Daily apparent revolution: Like all celestial bodies, the moon appears to revolve around the Earth, once every 24 hours.
- Daily growth and shrinking:
- Synodic revolution:
- Sidereal revolution:
- Secular slowing of the moon’s motion:
- Monthly growth and shrinking:
- Rotation on its axis:
- East-west Libration:
What are the 3 movements of Moon?
As the stars appear to move westward because of Earth’s daily rotation and its annual motion about the Sun, so the Moon slowly moves eastward, rising later each day and passing through its phases: new, first quarter, full, last quarter, and new again each month.
